/SPECIFICATION forming part of Letters Patent No. 274,920, dated April 3, 1883. l

Application tiled August 14, 1882. (No model.)

To all lwhom it may concern:Y

Be it known that we, SAMUEL DAY and REASQN DAY, of Delavan, in the county of Tazewell, in the State of Illinois, haveinvented an Improvement in Gnltivators; and wedo hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe annexed drawings, making a .part'ofthis specilicatiomin which like letters of reference refer to like parts, and in which- VFigure l represents a plan; Fig. 2, a side sectional view.

This invention is an improvement upon a cultivator patented by Samuel Day, November l0, 1868, No. 83,838, and relates to a means of changing the direction of the line of draft of the cultivator relative to the tongue, for the purpose of guiding the machine.

Thev object of this invention is to produce the maximumvariation between the cultivator and its tongue with the minimum movement of the hand applying the force consistent with the amount of strength convenient to be used.

B B represent part ot the frame-work of the cultivator, and A the tongue, pivoted at O andthe cast-metal bridge C, which is bolted at its ends tosaid bar B'. upon the upper side, at its center, a boss, J,

and in line behind it, with their centers about` two inches apart, a second boss, having through its center a bolt-hole countersnnk beneath. The boss J must be no higher than the base of the perforated boss K. The link E, which we make about one foot long, has at one end a slot, G, at the other end an opening to lit the boss J, and at about four inches from said opening a holefor thebolt F. The T-shaped link D is pivoted upon the boss K, being held thereat by the bolt` and washer H. To the ends of thearms are fastened rods BB, which come together as they leave said link D, and are secured in the handleS. Through the slot M goes the bolt F, which holds together the two links D and E. A bolt fastened into the tongueA projects up through the slot Gr of said link E, and the link D, being over the Said bridge C has the end Gr of the `link E is decreased, and by` 'lengthening said distance the throw of said link E, and conseqnentlyof the tongue A, is increased. If the throw of the tongue A relative to the handle S is increased too great a degree, so much Strength will be required to move said handle S as to make the cultivator diftcult to guide. By experiment we have found the proportions given above to be practically the best. p

In operating this cultivator the driver, who sits upon a seat directly behind the pivotal point O of the tongue, grasps with one hand the handle S, holding it in line with the line of draft of the cultivator if he desires to go straight ahead, but pressing it to one side or the other, according to which Side he wishes to steer the cultivator.

What we claim4 as our invention, and for which we desire Letters Patent, is as follows:

1. The tongue A, cultivator-frameB B', and bridge C, in combination with the link D, having slot M, rods B B, and handle S, and the link E, having slot G and bolt F, substantially as and for the purpose set forth.

2. A cultivator-frame, B B', tongue-A, pivoted thereto, and bridge C, having bosses J and K, in combination with the slotted link E, having bolt F, and slotted link D, having a movinglever.

In testimony that we` claim the foregoing invention we have hereunto set our hands this 31st day of July, 1882.
